Regression was introduced in 91c85ec86b
The openal-soft version 1.19.1 tried to use semaphores created by sem_init,
which are not supported on macOS, so they just didn't work at all. This was
leading to an event loop thread spin-waiting instead of a normal sem_wait.
In the v1.19 upstream branch GCD semaphores are used on macOS.
We ask the developer to obtain his own api credentials, because
the bundled 'api_id' / 'api_hash' are strictly limited by the server.
The old credentials still could be used for test purposes,
but the developer will need to explicitly opt-in to use them.
Some tests were disabled by a crashpad patch because the changes to make
them work with new SDK are relatively big and no need to backport them.
Fixes#4353.
After adding the libtgvoip submodule its project was created by GYP
outside the project folder, because the relative path to libtgvoip.gyp
is "../ThirdParty/libtgvoip/" and projects are created in the same
relative folders.
Now we place MSVC and Xcode projects in tdesktop/Telegram, so the
libtgvoip project is created at tdesktop/ThirdParty/libtgvoip.
Also add some more decoders in ffmpeg configuration (wav).
Also stop audio device restart on PKEY_AudioEndpoint changes.
Also deduce channel layout from channel count in ffmpeg loaders.
Something has changed in Qt libraries remote layout so now the perl
init-repository script from the old Qt version doesn't work anymore.
We init the submodules using script from the latest Qt version and
after that we checkout the desired version by tag in all submodules.
